That said, I'll never dragrace because there are no tracks in this country.The unsprung weight is decreased because the IRS is solid with the frame, only the arms move, instead of the entire stick.Pro's:- ride quality, it's a lot less nervous, jumpy, smooth as silk on higher speeds and in corners and on bad roads.- traction, a lot more and predictable traction on streets/bumps/coming out of corners.- gives the car a more solid, relaxed feel overall.- Looks, obviously.Con's:- Weight, though unsprung weight is reduced. I didn't really notice the difference of the increased weight but went from 3.27's to 3.55's in the process which may have set that off.- Price, don't think just the IRS is enough. You'll HAVE to do the bushings (delrin), brakelines, exhaust, etc. Do it right the first time trust me.- Breakage, which I think is bullshit if you have a streetcar. The terminators break them because they have 600+ hp, don't upgrade the bushings and don't strengthen the diff cover which will result in wheelhop sometimes. 9 out of 10 IRS breakages happen on the strip with slicks and a stock(ish) IRS and people who don't let off when it starts hopping.There PLENTY of very high horsepower guys running a well prepped IRS (read: bushings, diff brace, etc) who never have problems and wouldn't change the IRS for anything.The reason some go with the SRA is because they so the strip VERY often, have ridiculous horsepower numbers, and mostly don't care for the pro's of the IRS. (because racecar). In that case, I can completely understand, if you don't care for the ride quality and just want the strongest option back there to prevent braking things and being able to launch as hard as you can.Most importantly: if you plan on running the IRS, mod that s.o.b. while it's still out of the car. Get all the correct bushings, a diff brace, good springs/shocks, and swap it in! A good prepared IRS will not wheelhop most of the time (except for cold conditions/bad tired) and wheelhop is what kill the IRS. That said, mine hops sometimes when it's wet and cold and I haven't broken anything in over a year of daily driving. Just let off and be warned.</blockquote>
